The biochemical characterization of lysosomes has so far depended on purification methods based on either density gradient centrifugations or magnetic purification of iron-loaded organelles. Owing to dramatic changes in lysosomal density and stability associated with lysosomal diseases and cancer, these methods are not optimal for the comparison of normal and pathological lysosomes. Here, we introduce an efficient method for the purification of intact lysosomes by magnetic immunoprecipitation with antibodies against the vacuolar-type H1-ATPase.
